DEFINITIONS OF FT8 CONTROL HOUSE COUNTERS The following counters are used for FT8 gas turbines. If the unit is a TWINPAC™ or a SWIFTPAC™, then each engine (A and B) will have separate counters. POWERPAC™ and MOBILEPAC™ installations are equipped with a single set of counters. START Counter The START counter cycles when light-off is detected (a 25°F rise in average EGT). CYCLE Counter Cycles when the gas generator average EGT reaches 80 percent of base-load EGT. TOTAL FIRED HOURS Operates when the second fuel shutoff valve, either liquid or gas, opens. Stops when the second fuel shutoff valve closes. LIQUID FUEL FIRED HOURS Operates when the second liquid fuel shutoff valve opens. Stops when the second liquid fuel shutoff valve closes. GAS FUEL FIRED HOURS Operates when the second gas fuel shutoff valve opens. Stops when the second gas fuel shutoff valve closes.

NOTE

SECTION 1 - PURPOSE 1.0 Introduction This manual is intended to be used by personnel who will be conducting day-to-day operations and minor maintenance tasks associated with the operation of the FT8 TWINPAC™, SWIFTPAC™, POWERPAC™ and MOBILEPAC™ electric power generating units. The operator must have prior knowledge of and specific training on, the equipment. Details of the systems involved, required specifications, specific maintenance schedules and procedures are contained in other publications. Refer to SECTION 2 - TWINPAC™, SWIFTPAC™, POWERPAC™ and MOBILEPAC™ APPLICABLE PUBLICATIONS AND DOCUMENTS for a list of applicable publications and documents. A prerequisite for the successful application of this manual is that all equipment has been fully checked-out, commissioned, accepted by the owner and certified for normal operation. This manual covers the latest updated TWINPAC™, SWIFTPAC™, POWERPAC™ and MOBILEPAC™ FT8 engine configurations with dual fuel, water injection and remote monitor and control. Not all sites will be equipped with all the options covered in this manual. The TWINPAC™ is a dual engine field assembled unit. All interconnection wiring is field terminated and much of the piping is field fabricated and installed. Complete systems integration, calibrations and checkout are accomplished at the installation site. The SWIFTPAC™ is a version of the TWINPAC™ specifically designed for fast installation in the field. Many of the components are modular, the interconnecting wiring is pre-manufactured with quick disconnect cables and the piping is prefabricated. Partial systems integration, calibrations and checkout are accomplished at the factory thus reducing construction time at the installation site. The POWERPAC™ is a similar generating unit with a smaller generator and a single engine. The MOBILEPAC™ is a trailer mounted single engine generating unit. The generator, gas generator, power turbine and lube oil systems are mounted on one trailer. The control house and hydraulic start unit are mounted on a second trailer. The trailers are positioned at the site, interconnecting cables and prefabricated hoses are connected. After connection to fuel and water supplies as required and connection to the high voltage distribution system, the unit is ready to generate power. Systems integration, calibrations and checkout are accomplished at the factory. The unit is readily relocated. The overall operation of the unit and sub systems is very similar between the various configurations. Comments are added where specific functions or operations differ for a particular configuration. The various screens appearing on the Man Machine Interface (MMI) are similar in function but may differ in appearance between unit types and sites. Screens are identified in this manual by a number (1, 2, 3, etc). Where functionality is similar but appearances differ the screens are identified with the same number but with an alpha suffix (1A, 1B, 2A, 3A, 3B, 3C, etc). Several of the button icons have replaced the functional text description with symbols. The function of these buttons is described by popup windows when the curser is positioned over the button.

A. Manual – The unit proceeds through the start cycle with either a single engine or double engine start. The generator is ramped to 2910 to 3492 NP speed and waits for further Operator input. See SECTION 9 – NORMAL SYSTEMS OPERATION, Paragraph 9.3 – Auto Stop and Paragraph 9.5 - Manual Stop for manual operation of the machine.

B. Automatic – The unit proceeds through the start cycle with either a single

engine or double engine start. The generator is ramped to 2910 to 3492 NP speed and the synchronizer is enabled. The synchronizer will raise or lower speed and generator voltage, the generator is paralleled to the grid and the 52G main breaker closes. The machine loads at the selected load rate to either base load where it will operate on EGT control or to the selected program load where it will maintain that set point on NP control.

4. Set Voltage Regulator

Select MANUAL or AUTOMATIC voltage regulator operation from the 90-VT switch.

A. Manual – If the voltage regulator is placed in manual control, the control system

will automatically set the Twin Pac operating mode to MANUAL. See SECTION 12 – ABNORMAL OPERATION, Paragraph 12.6 – Monitoring System Failure.

B. Automatic -This is the normal operating mode for the voltage regulator. When

in Automatic, the Operator has the option to adjust power factor or MVAR and the regulator will maintain that set point. See SECTION 7 – SETTING OPERATING PARAMETERS, Paragraph 7.2 – Start/Stop Screen Operator Settings.

NOTE

The voltage regulator must be set to AUTOMATIC mode to allow AUTOMATIC operation of the TWINPAC™ or SWIFTPAC™.

SECTION 9 – NORMAL SYSTEMS OPERATION

9.0 Introduction

SECTION 9 – Normal Systems Operation outlines procedures for both automatic and manual starts, automatic and manual stops, manual synchronization, single engine operation, fuel transfer, synchronous condensing and black start. 9.1 Auto Start for Power Production from the Standby Mode. SECTION 8 – SYSTEM SETUP, Paragraph 8.1 – Standby for Normal Operations sets up the unit for automatic operation from standby. The unit is shutdown; the green READY TO START banner is illuminated and the Start A, Start B and Start Both icons are outlined on the Start/Stop page. See Screen 6, Screen 6A. The unit may be operated locally or remotely. Balance of plant (BOP) systems are set for normal automatic operation.

1. Click on the Street Light icon to open the pull down menu.

2. Select Start/Stop to open the Start/Stop page.

3. Select Start Eng A, Start Eng B, or Start Both to display the START pushbutton. The Start Both option will probably be the most common choice.

4. Place the cursor over the selected pushbutton and click.

5. After the start initiates, close the pushbutton window by clicking on the Open Book icon

in the lower right corner of the window. The control starts the BOP equipment including the gas compressor, SCR blowers, ammonia system and de-mineralized water system as required. The SCR purge is completed. The control initiates the start sequence for the TWINPAC™, SWIFTPAC™, POWERPAC™ or MOBILEPAC™. Engine A starts then engine B starts. The operator may select the first engine to start on the Start/Stop screen. The generator accelerates to synchronization speed and builds voltage on the stator. The synchronizer energizes and matches the generator voltage and frequency to the bus. The 52G breaker closes and the machine loads at the preset rate to the preset load.

The synchronizing process may be observed by watching the front of the automatic synchronizer on the Monitor panel (In the local control house only.) By turning on and observing the synchroscope the Operator may predict the breaker closure command from the synchronizer. See Paragraph 9.4 – Manual Synchronization. Turn off the synchroscope after breaker closure. The engine starting sequences may be monitored by clicking on the Start Sequence icon on the Start/Stop screen or by selecting the Start Sequence option from the Street Light pull down menu. See Screen 68. The unit operating sequence and systems run status are shown on the display on the right hand side of the Start/Stop screen.

58

If a single engine is started the second engine may be started any time the green READY TO START status is illuminated for that engine. 9.1.1 Alternate Auto Start for Power Production from the Standby Mode

1. Selecting the Unit Control option from the Street Light icon and following procedure in step 3 above is an alternate starting method.

9.2 Auto Stop. One or both of the TWINPAC™ or SWIFTPAC™ engines or the POWERPAC™ or MOBILEPAC™ engine may be stopped at any point after a start command is issued. If a single engine stop is initiated after a start both command is issued, the other engine will continue in the sequence until further Operator action is initiated.

1. Click on the Street Light icon to open the pull down menu.

2. Select Start/Stop to open the Start/Stop page.

3. Select Stop Eng A, Stop Eng B, or Stop Both to display the STOP pushbutton. The

Stop Both option will probably be the most common choice..

4. Place the curser over the pushbutton and click.

5. After the stop initiates, close the pushbutton window by clicking on the Open Book icon in the lower right corner of the window.

If a SINGLE ENGINE STOP is selected, that engine will shed load on NH control and decelerate to min NH. After a 5-minute cool down period the fuel valves close and the engine windmills until it is restarted or until the running engine is stopped. If a single engine STOP is initiated, that engine may be restarted any time the green READY TO START status is illuminated and the Start icon for that engine is outlined. If a STOP BOTH command is issued, both engines unload on NH control to approximately 1.5 MW. An automatic VAR shed command is issued to the automatic voltage regulator and VARs are reduced to zero. At 1.5 MW the 52G main breaker opens. The engines decelerate to Min NH and cool down for 5 minutes after which the fuel valves close. The gas compressor and BOP systems shutdown. The GT and generator lube oil systems continue to operate to allow the generator rotor to stop rotating and for PT lubrication and cooling. At the end of the GENERATOR COAST DOWN period all systems shutdown and the unit is in standby ready for the next start. The engine stopping sequences may be monitored by clicking on the Stop Sequence icon on the Start/Stop screen or by selecting the Stop Sequence option from the Street Light pull down menu. See Screen 9. Time remaining in the engine cool down period is shown on the Stop Sequence screen.

59

Time remaining in the GENERATOR COOLDOWN period is shown on the Start/Stop screen and on the Gen Lube Oil screens. See Screen 6 and Screen 49. The unit operating sequence and systems run status are shown on the display on the right hand side of the Start/Stop screen.

9.2.1 Alternate Auto Stop 1. Selecting the Unit Control option from the Street Light icon and following steps from

9.2.3 is an alternate stopping method. 9.3 Manual Start. The start sequence is fully automated and may not be altered by the Operator. Selecting MANUAL from the 43-2M switch on the Operator’s panel and indicated on the Start/Stop screen, results in a normal start of a single or both engines and the generator being accelerated to near synchronization speed. The generator field is excited and terminal voltage builds to a nominal bus voltage. The machine will then await further Operator action. All BOP systems, fans, lube oil systems, alarms and trips will function as normal. If the machine is being operated for inspection or maintenance, the Operator may choose not to build voltage on the generator by placing the voltage regulator in MANUAL by operating the 90VT switch on the Operator’s panel to manual and observing the status on the Start/Stop screen.

1. Operate the 43-2M switch on the Operator’s panel to MANUAL. Observe the status on the Start/Stop screen.

NOTE

The AUTOMATIC mode may be selected at any time during this procedure. If AUTOMATIC is selected, the control will function as described in Paragraph 9.1 from that point in the sequence.

A. To operate without building voltage on the generator, select manual voltage

regulator operation by operating the 90VT switch to MANUAL and observing status on the Start/Stop screen.

B. To return to normal generator operation and build voltage on the generator

after the start, operate the 90VT switch to AUTOMATIC and observe status on the Start/Stop screen. Voltage on the generator will build to a nominal bus voltage.

C. The Operator may manually build voltage on the generator by slowly operating

the 90VC-R switch on the Operator’s panel to the RAISE position and observing voltage on the three-phase Generator Voltmeter, KVG.

NOTE

Generator must be operating at 3000 RPM (50 Hz) or 3600 RPM (60 Hz).

D. In manual, the Operator may lower voltage on the generator by operating the

90VC-L switch on the Operator’s panel to the LOWER position and observing voltage on the three-phase Generator Voltmeter, KVG.

60

E. To return to normal generator operation operate the 90VT switch to AUTOMATIC and observe status on the Start/Stop screen. Voltage on the generator will control at a nominal bus voltage.

NOTE

The automatic voltage regulator (AVR) must be in the AUTOMATIC mode in order to select TWINPAC™, SWIFTPAC™, POWERPAC™ or MOBILEPAC™ AUTOMATIC mode.

2. Select a double or single engine start from the Start/Stop screen per Paragraph 9.1,

Step 3. The BOP and the selected engine(s) will start and accelerate the generator to Sync Idle. If the AVR is in AUTOMATIC, generator voltage will build to nominal bus voltage.

NOTE

The machine may be operated at this speed for inspection, troubleshooting or maintenance as necessary.

9.4 Manual Synchronization. The Operator may manually synchronize the machine to the grid for power generation and control load and PF/VARS. Water injection will operate automatically if WET operation is selected.

1. Start the machine per Paragraph 9.3, Step 2, with the AVR in the AUTOMATIC mode.

2. Observe generator frequency on the Generator Frequency Meter FG.

3. Observe bus frequency on the Bus Frequency Meter FB.

4. Observe generator voltage on the three-phase Generator Voltmeter KVG.

5. Observe bus voltage on the three-phase Bus Voltmeter KVB.

6. Match the generator frequency to the bus frequency by operating the 18-1 switch on the Operator’s panel.

NOTE

With the 52G breaker OPEN the 18-1 switch raises or lowers the generator rotor speed, NP. With the 52G breaker CLOSED the 18-1 switch raises or lowers generator output power.

7. Adjust the generator voltage to be slightly higher than the bus voltage by operating the 90VC switch.

NOTE

With the 52G breaker OPEN the 90VC switch raises or lowers generator terminal voltage. With the 52G breaker CLOSED the 90VC switch raises or lowers the generator PF/VARs.

61

8. Turn on the synchroscope by operating the 69SS synchroscope switch on the Operator’s panel to ON.

9. Observe the pointer on the synchroscope SYN and the illumination of the synchronizing

lights SL1 and SL2. The generator and bus are exactly in phase when the pointer is at the 12 O’clock position and the synchronizing lights are out.

NOTE

If the pointer rotation is clockwise (CW), the generator frequency is higher than the bus frequency. If the pointer is rotating in the counter-clockwise (CCW) direction, the generator frequency is lower than bus frequency.

10. Adjust the generator speed using the 18-1 switch to achieve a clockwise rotation of the pointer at an approximate rate of 15 to 20 seconds per revolution.

11. Recheck generator voltage per Step 7, this paragraph.

CAUTION

The generator must be in phase with the bus before closing the 52G breaker.

12. Operate the 52CS-C switch to close the 52G breaker when the pointer on the

synchroscope reaches the 12 O’clock position.

NOTE

The Sync Check relay 25SC monitors generator and bus voltage and frequency. It will only allow the breaker to close when both are within synchronization limits. It allows only a short “window” of time in which the 52CS-C switch will be allowed to close the breaker. A green LED on the face of the 25SC is illuminated during this open “window”. The machine will pick up approximately 1.5MW when the 52G breaker closes.

13. Operate the 69SS switch to the OFF position.

14. Observe megawatt output on the Generator Megawatt meter W.

15. Observe power factor on the Power Factor Meter PF.

16. Observe mega-vars on the Generator Mega-Var meter VAR.

17. Adjust the generator power output by operating the 18-1 switch.

NOTE

Generator output power will vary slightly with bus frequency, ambient temperature and ambient pressure.

62

18. Adjust the generator power factor and megavar level by operating the 90VC switch.

9.5 Manual Stop. If the machine is operating at Sync Idle or on line in either MANUAL or AUTOMATIC mode, the Operator may unload, open the 52G breaker and shutdown manually.

9.5.1 Manual Stop from Sync Idle

1. Enter a Stop Eng A, Stop Eng B or Stop Both command from the Start/Stop screen per Paragraph 9.2, Step 3.

2. If the machine has not been loaded and the Operator wishes to bypass the automatic 5-

minute engine cool down cycle, press the EMERGENCY STOP pushbutton. Fuel valves will close immediately and the coast down cycle will start.

3. Pull out the EMERGENCY STOP pushbutton, reset the lockout relays and control as

necessary.

9.5.2 Manual Stop from MANUAL On Line Power Generation

1. Observe power and megavar levels on W and VAR meters.

2. Use the 18-1 switch to lower generator output power to approximately 1.5 to 2 MW.

3. Concurrently use the 90VC switch to lower megavars to approximately 0 MVAR.

4. Operate the 52CS-T switch to the OPEN position to open the 52G main breaker.

5. Stop the engine(s) by selecting Stop Eng A, Stop Eng B or Stop Both command from the Start/Stop screen per Paragraph 9.2, Step 3.

9.5.3 Manual Stop from AUTOMATIC On-Line Power Generation

1. Place the machine in MANUAL mode by operating the 43-2M switch to the MANUAL position.

2. Follow steps outlined in Paragraph 9.5.2 - Manual Stop from MANUAL On Line Power

Generation

9.6 Single Engine Operation 9.6.1 Single Engine Operation With Other Engine Coupled (Windmilling). The machine may be operated as described in Paragraphs 9.1 to 9.5 with engine A or engine B operating alone. In this mode, the non-fired engine will rotate or “windmill” due to the airflow induced by the spinning power turbine. The windmilling engine should be considered to be in an operational mode. No maintenance operations are permitted. All normal safety precautions must be followed. The non fired engine will exhibit the following characteristics:

1. The Lube oil system will operate as normal. PT lube oil pressure will be normal.

2. NL and NH will be much lower than normal and will vary with ambient conditions.

63

3. The GG lube oil pressure will be lower than normal.

4. The-VACuum pump will operate.

5. Periodically the second lube oil pump will operate to provide additional oil to the GG. Lube oil pressures will change during pump operation. The GG lube oil pressure will increase and the PT lube oil pressure may decrease.

6. The windmilling power turbine will become hot and the enclosure temperature may rise.

The windmilling engine may be started at any time per Paragraph 9.1 - Auto Start for Power Production from the Standby Mode. 9.6.2 Single Engine Operation With Other Engine De-coupled. A special logic setup is required in a dual-engine configuration when there is a need to de-couple one side in order to facilitate a single engine configuration operation. This setup gives the ability to have an engine or power turbine out of service while the other power turbine and engine is operational. The mechanics of the setup involves disabling the Power Turbine lube oil system operation of the unit that is de-coupled and possible change of the Np signal to the overspeed switch.

1. Remove the aft flexible coupling on the output shaft of power turbine to the electrical generator. Ensure proper support procedures and tools per the maintenance manual are followed to support the output shaft.

2. The following is done to enable the Disengage logic:

• The 86 lockout relay corresponding to the de-coupled engine must be

tripped. This can be done by manually tripping the lockout coil.

• The Micronet/NetCon software tunable must be changed by accessing the GAP program “Category” and “Block” names. The applicable category and block are located in the MicroNet/NetCon. Common “Category” and “Block” name is common on units installed post Year 2000 and unique on pre-Year 2000 installations. Contact PWPS customer Support for the correct “Category” and “Block” name.

• Adjust tunable from False to True.

NOTE If the “A” side is de-coupled, it is required to make changes to the ST008A/B termination to the overspeed switch, since the default wiring scheme to the switch is driven only from the “A” side NP transducer.

9.7 Fuel Transfers. The starting fuel, gas or liquid, is selected by the Operator from the Start/Stop screen prior to initiating a start. The Operator may transfer to the alternate fuel at any time after the engines have started. It is not possible to operate one engine on one fuel and the other engine on the alternate fuel. It is not possible to operate on a “blend” of the two fuels except during the fuel transfer.

April 3, 2009 Page 1 of 1

2. Select start “A” or start “B” on the Start screen and initiate a normal start. Start Both

may be selected but it is only necessary to start one engine to enter synchronous condenser operation.

The engine will complete a normal start and accelerate the generator to synchronous speed. The synchronizer will automatically adjust voltage and frequency as necessary and close the 52G breaker. After the breaker closes the engine fuel valves will close and both “A” and “B” engines will windmill. 9.8.1 Synchronous Condenser Operation In VAR or Voltage Control Mode. The machine may be operated in VAR or Voltage control mode that can be selected from the VAR/Voltage Adjust screen, See Screen 65 or Screen 66. This screen is accessed from the Start/Stop screen. See Screen 6 or the Ancillary Generator screen, Screen 48. Set the VARS or Voltage as required, usually as directed by the System Operator or Load Dispatcher. 9.8.2 Synchronous Condenser Mode Operating Options. From synchronous condenser mode, the Operator has the option to stop or to generate power. To stop the machine and return to standby:

1. Enter a normal stop (Refer to Paragraph 9.2 – Auto Stop). The 52G breaker will open and the rotor will coast to a stop as during a normal stop from generation.

2. Select Parallel using the 43-3 switch to generate power.

To generate power:

1. Operate the 43-3 switch to Parallel. The engine used to initiate synchronous condenser will start and load as selected. To achieve full rated load with two engines, enter a normal start to the wind-milling engine.

9.8.3 Entering Synchronous Condenser Mode From Power Generation Mode. Synchronous condenser mode may be entered from the power generation mode. To avoid a possible power system perturbation it is recommended that the load on the machine be reduced prior to initiating synchronous condenser.

1. Initiate Synchronous Condenser using the 43-3 switch. The operating engine(s) fuel valves will close and the engine(s) will windmill. Operation will be as per paragraph 9.8.1 - Synchronous Condenser Operation In VAR or Voltage Control Mode.

9.9 Black Start. The black start mode allows the unit to start and supply power when the grid is dead or isolated to the main step up transformer connected to the FT8. The operator must manually transfer the FT8 control enclosure AC power feed from the Normal Source to the Alternate Source. To select Black Start Mode the Dead Bus Relay (DBR) must also sense a loss of AC power. Two Black Start operating modes may be selected: Isolated Droop Mode and Isolated Precise Mode. 9.9.1 Isolated Droop Mode. Generator circuit breaker is closed onto a dead bus. Generator frequency is allowed to vary with the load with up to 4 percent (2 cycles) droop. This mode is used when other generators are to be paralleled to the FT8 after it has energized station bus. 9.9.2 Isolated Precise Mode. Generator circuit breaker is closed onto a dead bus. Generator frequency is automatically maintained at 50 or 60 Hz. This mode is used when the generator is to be

65

66

operated on the bus alone and does not permit paralleling by other generating systems. Isolated Precise Mode should only be selected when the TWINPAC™, SWIFTPAC™, POWERPAC™ or MOBILEPAC™ will be the sole generating source over a long period of time and automatic isochronous frequency control is desired.

NOTE

If operating in Isolated Precise operation and it is desired to switch to Isolated Droop, the operator should be prepared to adjust frequency as it may fall lower than expected. If operating in Isolated Droop and the FT8 has been synchronized and paralleled with other generators the unit can be transferred to normal Parallel mode. Although the Dead Bus Relay will prevent the breaker closure onto a live bus, it is good operating practice to ensure that the bus to be closed upon is not energized before closing the breaker. Also check that excessive dead load is removed.

9.9.3 Sequence of Operation for Automatic Isolated Droop Black Start Operation

1. Operator preliminary steps:

A. Personnel notification of start expectation and start time

B. Inspect gas turbine and generator enclosures for operational status

C. Generator circuit breaker OPEN green light ON.

permissive from the control system is at 3550 RPM. The Dead Bus Relay will initiate Dead Bus Mode in the XMC Synchronizer. The Synchronizer will monitor the bus voltage and if the bus voltage remains below a threshold value will close the breaker after the internal timer period expires as long as the generator voltage is within the acceptable band of 100 to 130 volts.

I. As external loads are added to grid, unit will instantaneously load to the current

load up to BASE LOAD. Generator frequency will follow the four percent droop slope and should be adjusted using the LOAD CONTROL SWITCH (18-1) to maintain frequency of approximately 60 Hz as loads are added. EGT Control will be illuminated on the ANALOG PAGE when Base Load is reached.

CAUTION

Loading in excess of the BASE LOAD schedule will result in a reduction of frequency and voltage, and the Unit could be forced into a 86G-2 trip because of over-current or under-frequency. Continued emergency operation, therefore, will depend upon the shedding of excessive load by the customer’s operating system.

SECTION 10 – MANUAL OPERATION OF SYSTEMS

10.0 Introduction

CAUTION

Manual operation of the systems may not be considered when the unit is in an operational mode. The unit must be shutdown and the systems must be safe to operate independently. It may be necessary for the unit to be declared out of service.

10.1 Engine Wash. The engine compressors should be water washed periodically to maintain operational efficiency. See the Standard Maintenance Practices Section of the Gas Generator Maintenance Manual for recommendations and optional procedures. Contact Pratt and Whitney Power Systems Customer Support for additional instructions. Each engine is washed separately. Detergent can be applied prior to the water wash cycle if desired. Detergent can be applied manually or by using the optionally purchased detergent cart and control software. Refer to Section 14 of the GG8 Maintenance Manual for manual application. 10.1.1 Detergent Wash. A detergent wash may be performed manually or, if the optionally purchased detergent cart is available, automatically. For manual washing procedures, refer to Section 14 of the GG8 Maintenance Manual. The automatic detergent wash cycle rotates the selected engine on the hydraulic starter, sprays detergent into the rotating engine for 120-seconds (tunable), stops the rotation and starts a 15-minute soak timer. The wash permissives, listed below, must be satisfied as shown in green on the water wash screen. See Screen 52. 10.1.1.1 Detergent Wash Procedure

NOTE

Refer to PWPS Operations and Maintenance Manual, Ancillary Systems, Water Wash Section for detailed operating instructions of the water wash cart. Water wash cart pumps are either pneumatically or electrically powered.

General connection and filling procedures are as follows:

1. Using the supplied hoses, connect the cart to the water supply and the inlet of the gas turbine.

2. Connect the air supply or the electrical power supply to the water wash cart, as required. 3. Select an approved detergent from the list provided in the GG Maintenance Manual and

determine the water to detergent ratio if mixing with water is required.

74

4. Add detergent to the tank. If the addition of water is required, open the water supply valve

and inlet valve to the cart. Slowly open valve at the bottom of the tank to allow water to fill. Use the level gage to add the appropriate amount of water. Close the tank valve.

5. Close the water inlet valve. Open the cart discharge valve and tank valve. Start the pump

when ready to begin the detergent cycle.

CAUTION

The electric motor-driven pump is not designed for continuous dead-headed operation. Energize the pump just prior to starting the wash cycle and shutdown the pump as soon as possible afterwards. The pump can be operated for up to approximately one-half (1/2) hour with no flow before overheating.

Both overspeed tests were performed and successfully tested during the commissioning of each unit. Some 50 Hz sites have the overspeed trips set at 3450 RPM.

CAUTION

Simulation of overspeed tests is not acceptable. Overspeed Settings 60 Hz Micronet 3960 AirPax 3960 50 Hz Micronet 3300 AirPax 3300 50 Hz Micronet 3450 AirPax 3450

10.7.1 Overspeed Test Preparations

1. Ensure that the area is cleared of all non-essential personnel and that personnel involved in the test procedure have been fully briefed regarding the test plan.

2. Coordinate locally as required to assure that the turbine/boiler (If so equipped) unit is

adequately purged prior to each start. 3. Assure that all engine control trips or shutdowns are operational.

4. Prepare the unit and auxiliary systems to start and run.

5. Ensure that power to the MAVR is turned off and tagged to prevent building voltage on

the generator. The switch is located on the back wall of the operating cabinet.

NOTE After selecting the O/S test, do not reset software or the selection will be lost.

10.7.2 Overspeed Test Procedure. While the engine is shutdown, clear all start permissives and confirm that both engines are ready to start.

1. Select “Overspeed Tests” from the Scales icon pull-down menu, See Screen 16.

2. Click to select the desired overspeed test (Woodward or AirPax). Note that when no test has been selected, the NP overspeed set-point is set to 3300, 3450 or 3960 RPM. See Screen 22, Screen 22A. Also, note that an overspeed test may be selected only when both engines are indicating ready to start, but start has not been initiated. Once overspeed is selected, the Ice monitor will indicate which overspeed test has been selected (in highlighted red text). The NP overspeed test can be aborted at any time by simply pressing the “off” push-button.

79

3. If the Woodward control overspeed test is being selected, the following are expected:

See Screen 23, Screen 23A.

A. NP overspeed trip set-point for the Woodward control is decreased 10 RPM from 3300 to 3290, 3450 to 3440, or 3960 to 3950 (confirm on monitor display)

B. The maximum NP reference is increased to allow the NP reference to move up in manual operation.

C. The NP overspeed trip set-point for the AirPax system is preset from the factory to 3300, 3450 or 3960 RPM.

D. By lowering the Woodward control set-point, overspeed detection by the Woodward control will occur at 3290, 3440 or 3950 NP before the AirPax set-point at 3300, 3450 or 3960 RPM.

4. Put the operating mode of the unit into Manual Mode and perform an engine start. 5. Manually raise the NP reference speed toward the overspeed trip point, and confirm

that the unit trips at 3290, 3440 or 3950 RPM NP speed as expected. Manually decrease NP speed to 3285, 3445 or 3945 RPM; then, increase the speed very slowly toward 3290, 3440 or 3950 rpm.

6. Similarly, if the AirPax overspeed test is selected, the following are expected: See

Screen 24.

A. NP overspeed trip set-point for the Woodward control is increased 10 RPM from 3300, 3450 or 3960 to 3310, 3460 or 3970 RPM (confirm on monitor display)

B. The maximum NP reference is increased to allow the NP reference to move up

in manual operation. C. The NP overspeed trip set-point for the AirPax device is preset to 3300, 3450

or 3960 RPM from the factory. D. By increasing the Woodward control set-point, overspeed detection will occur

from the AirPax set-point rather than the Woodward control overspeed set-point.

NOTE

The AirPax switch receives an Np speed signal from a power turbine speed sensor, ST008A or ST008B. When testing the “A” engine, insure the Airpax is connected to ST008A and when testing the “B” engine insure the Airpax is connected to ST008B. Refer to PWPS drawing XXX-187-E101D, Sheet 14 for wiring. Restore wiring to ST008A (as shipped) after testing the “B” engine.

80

7. Again, confirm the operating mode of the unit is Manual Mode and perform an engine start.

8. Manually raise the NP reference speed toward the overspeed trip point and confirm that the unit trips at 3300, 3450 or 3960 RPM NP speed as expected. Manually increase the NP speed to 3295, 3445 or 3950 RPM; then, very slowly increase toward 3300, 3450 or 3960 RPM.

9. Reset the Overspeed Speed Relay by pressing the green lighted button on the operating panel.

10. Reset the system for normal operation. See SECTION 8 – SYSTEM SETUP, Paragraph 8.1 – Standby For Normal Operations.

SECTION 11 – DATA SYSTEMS 11.0 Introduction. The Monitoring System provides data to the Operator that is useful for normal operations, records keeping, troubleshooting and problem diagnostics.

11.1 Fast Data Logger. The Micronet constantly monitors all of the operating parameters of the TWINPAC™, SWIFTPAC™, POWERPAC™ or MOBILEPAC™ and its auxiliary systems. When the control system issues an emergency stop or trip, the data logger saves approximately one minute of data before the trip at the very fast scan rate used by the control. This data is then automatically sent to a file for analysis by plant personnel or PWPS Engineering using the Control Assistant program. See SECTION 13, Paragraph 13.5 – Control Assistant. After a trip the data logger resets itself to record the next incident. 11.1.1 Operator Recorded Data Options. The Operator has the ability to select the time recorded after a trip, can manually initiate the recording of data or can inhibit recorded data from being overwritten. To select time:

1. Open the pull down menu under the Scales icon. See Screen 16.

2. Select Data Logger to open the Ancillary Data Log control screen. The Operator is advised if there is data available in memory. See Screen 17.

3. The Operator may adjust the time that data is recorded after a trip. The default

setting is zero seconds.

4. Place the curser over the time window. The window becomes outlined in red.

5. Enter the time in seconds to record after a trip from the keyboard and press “Enter”.

NOTE

This time is deducted from the time before a trip. Usually 5-seconds is sufficient.

The Operator may initiate a data log recording.

1. Place the curser over the Stop Sign icon. The icon is outlined in red. 2. Click on the Stop Sign icon to initiate a data log recording. The Micronet will

record a data log and send it to the monitor. While transmitting data the logging function is disabled and the display is as shown on Screen 18.

To inhibit recorded data from being overwritten:

1. Place the curser over the Green Check icon. The icon is outlined in red.

2. Click on the icon to inhibit. A Red X icon is shown and the advisory box indicates INHIBITED in red.

84

3. Click on the Red X icon to return to normal.

After the data has been recorded and sent, the Micronet will revert to the monitoring mode and will start recording new data. Since a data log was not initiated, there will be no recorded data and the display will be as in Screen 19. After approximately one minute, the display will re-appear as in Screen 17. The log file will reside in the ICE monitor computer in F:\Inetpub\ftproot\Datalogs\Unit3\name.log. The name will be time stamped and will be in the format 172.17.3.1 – Tuesday January 27 2003 81416.log. The name may be changed using normal Windows tools, but MUST retain the file extension .log. The data may be graphed and viewed using Control Assistant. See SECTION 13 – MAINTENANCE AND TROUBLESHOOTING, Paragraph 13.5 – Control Assistant. 11.2 Trends Data System. The ICE Monitoring system monitors, displays and records virtually all of the analog and digital inputs to and outputs from the control system to devices in the field. Analog data is stored from thermocouples, RTDs, position transducers, speed transducers, pressure transducers, level transducers and data from the CEMS equipment. Many digital inputs and outputs are also stored including commands to and from the Micronet. These data can be displayed in real time or in history graphically using the trending option of the monitor. 11.2.1 Trends Screens. The Trends system is accessed by clicking on the Graph icon. See Screen 27. The resulting pull down menu allows access to Unit, Engine A or Engine B predefined trends graphics.

from the keyboard and click OK. 11.2.3 Trend Screen Data. Data is displayed in graphical form plotted as a function of time with the magnitude of the data on the vertical axis and time on the horizontal axis.

• The first column of the graph, Trend, describes the data point. The F4 key will toggle the display between the tag number and the verbal description.

• The second column, Value, displays the magnitude of the data.

• The third column, Units, describes the units in which the variable is measured. The F5

key will toggle the system between Metric and English units.

• The Max and Min columns show the maximum and minimum values of the range for that variable on the graph. The ranges may be adjusted as described above.

11.2.4 Trend Screen Time. Time and date data are shown in the row under the main graphic.

• The data on the left end of the graph shows the date and time at the start of the trend.

• The data on the right end of the graph shows the date and time at the end of the graph.

86

• The data in the mid point of the graph shows the date and time at the curser.

• The “Period” is the time between data points comprising the data trace. The minimum time is 0.1 second.

• The “Span” is the time between the start and end of the graph.

The time scale on the horizontal axis of the graph may be adjusted and manipulated. The “Period”, “Span”, “End Time” and “End Date” may be adjusted by clicking on the value to open a numerical keypad window and entering the desired value from the screen keypad or the keyboard and clicking “Enter”. Clicking on the body of the graph will call up a white vertical curser. Position the curser by dragging it with the mouse or by using the “Curser Control” arrow buttons. The ‘Right” pointing buttons move the curser later in time and the “Left” pointing buttons move the curser earlier in time. The center button removes the curser from the graph. The single arrow buttons move the curser one period. The double arrow buttons move the curser 10 periods. The value of the trended points in the “Value” column will be the value at the curser. Time at the curser is also displayed. The Trend graph may be moved earlier in time by using the “Trend Control” arrow buttons. The trend is moved to the real time monitor by clicking on the extreme right hand “arrow/stop” button. The graph presentation may be modified to assist with data analysis by using the centrally located function buttons. From top left to right their function is as follows:

The Trend selection prints a color-coded or black and white graph on white paper. It allows the Operator to add a comment such as a title to the graph and to select a printer setup. 11.2.6.2 Screen Shot. The Screen Shot selection prints the displayed screen. The Operator has the option for limited customization of the print using standard Windows tools. The background will be printed in black or gray scale. This selection uses large quantities of printer ink and the Trend selection is usually the more common choice. 11.2.7 Individual Parameter Trends. Trends graphs of individual parameters may be accessed from various data screens such as the Analog Screen, Lube Oil System Schematic screens, etc. Limited operations on the graph are permitted using tools similar to those described above. Moving the curser over the analog value of interest to produce a red box outline and clicking on the box accesses individual trends. 11.3 FT8 Engine Log

NOTE

Not all sites are equipped with FT8 Engine Log capability. Data on the previous start and trip are logged and stored. Data includes time of start and fuel and loading mode. Breaker close and open times are also recorded. The log is closed when the unit shuts down. The stop time and run duration are logged. The “First Ins” causing an engine trip, engine controlled shutdown, engine controlled drive back, unit trip, unit controlled shutdown and unit drive back are shown. The “First In” is shown as a whole number. To see a verbal description, place the cursor over the number that will result in the value being boxed in red, and click inside the box. The box will highlight in yellow and a verbal description will be shown in a yellow text box.

88

After shutdown, the log data is stored on the F-drive of the ICE Monitor computer in the following folder:

F:\cit521\data\datafiles\datalog\unit(#)\log.dbf

In order to view the data from the previous runs, copy the selected logs to a separate folder, then open the folder and the desired file.

CAUTION

DO NOT open the file directly from the ICE Monitor folder. This will corrupt the entire log file and the data will be lost.

89

SECTION 12 – ABNORMAL OPERATING CONDITIONS 12.0 Introduction. The equipment is fully monitored and protected by the control system. In the event that a parameter goes out of predetermined limits or the sensing device fails, the control will automatically initiate action. An advisory is sent to the Operator via the alarm screen, see Screen 102, and is logged on the alarm summary. See Screen 103. 12.1 Alarms. An alarm is an advisory that a parameter has changed from a normal state to an abnormal state, or that an event outside of normal operation has occurred. The alarm will be shown on the alarm screen, the alarm summary screen and the three-line alarm display on the bottom of the ICE monitor screen. An audible alarm horn will sound.

If the alarm is such that damage is not eminent, the machine will continue to operate. The Operator must investigate the condition and initiate remedial action, however. The Operator may acknowledge the alarm or perform other tasks as described in SECTION 6 – WORKING WITH ALARMS AND EVENTS LOG. The alarm will remain on the alarm screen until the parameter returns to a normal condition.

See the project specific Alarm and Trip List document XXXX-189-C005L, for a complete listing of alarms.

12.2 Controlled Drive-back (CDB). If the condition becomes more severe or if it is a condition where an operating limit is exceeded but does not pose an immediate danger, the control may initiate a controlled drive-back. The power level of the machine will be reduced until the parameter is again within operating limits. If the parameter does not return to acceptable limits, the power level will continue to lower until the 52G breaker opens and the machine completes a normal shutdown.

The cause of the drive-back and the drive-back condition will be alarmed as above. The Drive-back Reset button on the Start screen will become active.

Controlled drive-backs may be initiated for individual engines or for the unit that will cause both engines to reduce power.

The Operator may be able to cure the condition that is causing the drive-back and resume normal operations. If the condition is remedied, opening the Start screen and clicking on the Drive-back Reset button will reset the drive-back. The control will drive the power up to the previous operating set-point and normal operations will continue. See SECTION 5 – RESETTING DEVICES AND SYSTEM, Paragraph 5.6 – Controlled Drive-back Reset.

If the driveback condition cannot be cured while on line, the machine can continue to operate at a reduced power level as long as the parameter remains within safe limits.

See the project specific Alarm and Trip List document XXXX-189-C005L, for complete details.

12.3 Controlled Shutdown (CSD). If the condition becomes more severe or if it is a condition where an operating limit is exceeded and continued operation may become dangerous or cause equipment damage, the control will initiate a controlled shutdown. The machine will respond as if a normal stop were initiated except that a green Ready to Start light will not illuminate. See SECTION 9

90

– NORMAL SYSTEMS OPERATION, paragraph 9.2 – Auto Stop. The engines will shed the load, the 52G breaker will open and the engine(s) will shutdown after cool down. At engine shutdown the lockout relay(s) will trip and require a manual reset by the Operator.

The cause of the CSD and the CSD condition will be alarmed, as above. Controlled shutdowns may be initiated for individual engines or for the unit that will cause both engines to shutdown. A CSD below idle speed will result in an engine trip. See the project specific Alarm and Trip List document XXXX-189-C005L for complete details.

12.4 Trips. Any condition that causes an immediate threat to safety or that will result in equipment damage will cause an automatic engine or unit trip. If the Operator notes a situation requiring a unit trip, he may initiate the trip by pressing the Emergency Stop pushbutton on the Operator’s panel. A trip results in an immediate opening of the 52G breaker and an immediate fuel chop to the engines. Lockout relays will trip and require manual reset by the Operator.

The trip may be initiated for individual engines or for the unit that will cause both engines to shutdown. Operation of the Emergency Stop pushbutton causes a unit trip.

If the engines trip from power an automatic cool down will be initiated by the control. When NP speed falls below 1200 RPM and the average EGT exceeds 400°F, the control will rotate the engine on the starter to cool. Rotation lasts approximately one minute or until the average EGT is less than 380°F. If the EGT climbs above 400°F, the control will again rotate the engine. This cycle may occur up to three times per engine. The cool down cycle will alternate rotations between engines if both trip. If only one engine trips and the other continues to operate, the tripped engine will not cool down on the starter. The cool down cycle will not initiate if the trip is initiated by the Emergency Stop pushbutton. Certain types of trips will not initiate the cool down cycle because rotation of the engine could result in additional damage.

The Operator may cancel the cool down by pressing the Emergency Stop pushbutton.

See the project specific Alarm and Trip List document XXXX-189-C005L for complete details.

12.5 Failed Devices or Sensors

CAUTION

It is not permissible to operate the equipment or systems with protective devices inhibited or defeated by using jumper wires, lifting wires, mechanically blocking switches, valves or other devices or by inhibiting trip functions in the control.

As the control monitors analog inputs, the logic applies two sets of criteria to the signal. The first criterion determines if the parameter is within the normal operating range. If the value is out of range, an alarm or other action is initiated as above. The second criterion determines if the value is within a

91

predetermined operation range for that particular sensor. If the value is out of range, the control determines that the sensor has failed and initiates action as above. A red X over the device tag name indicates failed sensors on the systems schematic screens. If a sensor indicates a failed condition after a maintenance operation or calibration, clicking on the Reset button on the Start screen may reset it. It is permissible to operate with up to two (2) EGT thermocouples (TC) failed. Each failed TC will be annunciated. The third failed TC will initiate a controlled shutdown (CSD) and will inhibit the start permissive for the affected engine

12.6 Monitoring System Failure. If the monitoring system fails during operation, the Operator will loose the ability to monitor data and alter most of the operating characteristics of the machine. If the system fails while the unit is shutdown, the machine cannot be started. The unit will continue to operate at the set points that were entered prior to the failure. The equipment will continue to be monitored and protected by the control but alarms, CDBs, CSDs and trips will not be annunciated or recorded. The alarm horn will sound if an event occurs but it will not be possible to silence the alarm. See SECTION 3 – MAN-MACHINE INTERFACE (MMI) OPERATION, paragraph 3.5 – Stopping the Monitoring System.

If the monitoring system fails and there is no remote monitoring capability, it is advisable to shutdown the unit until the necessary repairs are completed. If the unit is shutdown, it will be impossible to restart until the monitoring system is repaired. The unit may be safely shutdown using the steps below.

NOTE

It is not advisable to shutdown the unit from load by operating the emergency stop pushbutton.

1. Observe the system operating parameters, megawatts, megavars, power factor, generator amps and NP speed, on the analog gages on the Operator’s panel.

2. Select “Manual” using the 43-2 Mode Select Switch.

3. Adjust the generator excitation using the 90VC Volts/Vars Control Switch until the

power factor is equal to 1 and the MVARs are 0.

4. Adjust the generator output power using the 18-1 Speed/Load Control Switch until the load is at minimum, approximately 1.5 MW.

5. Open the 52G breaker by operating the 52 CS-G Generator Breaker Control

Switch to the “Trip” position.

6. Adjust the NP speed to minimum, approximately 3550 NP, using the 18-1 Speed/Load Control Switch.

7. Allow the engine(s) to cool at minimum speed for at least five (5) minutes.

8. Push the 5-1 Emergency Stop switch to shutdown the engines. The engines will

shutdown and the alarm horn will sound. It will not be possible to silence the horn.

92

SECTION 13 – MAINTENANCE AND TROUBLESHOOTING 13.0 Introduction. SECTION 13 - MAINTENANCE AND TROUBLESHOOTING provides information on operations to be routinely completed by the Operator.

NOTE

For systems maintenance procedures please refer to the Systems Maintenance Manual.

13.1 Battery System. The 24-VDC and 125-VDC battery racks are located in a cabinet at the air conditioner end of the control building. There is a battery charger for each battery bank between the personnel door and the MCC. The system can be monitored from screen 141. Batteries should be periodically inspected for cleanliness and for leaks. Terminals should be inspected for corrosion. Battery chargers should be viewed for any alarms or battery grounds. These alarms are also sent to the monitoring system. If a battery ground is present, the indicator lamps on the face of the charger will illuminate to show which leg of the battery is grounded. The lamps may be tested by operating the Battery Ground Test Switch to the left or right. Battery voltages should be read and recorded semi-annually. After a review of the cell data, an equalizing charge may be required. Move the Equalize Switch to the right to start the equalize charge.

An equalize charge is indicated when:

• The float voltage per cell is less than 2.18-VDC.

• A recharge of the battery bank is required in a minimum time period following an emergency discharge.

• The float voltage difference within a string of cells is greater than 0.10-VDC.

• Periodic records of individual cell voltages show an increase in spread since the

previous semi-annual readings.

13.1.1 General Operating Procedure The main control on standard units is the float/equalize switch, located on the front panel. This control allows the operator to select either the float or equalize output voltage mode. Float and equalize modes are two different output voltage settings, with the equalize voltage being slightly greater than the float voltage. The equalized mode is used to eliminate charge level differences between individual cells and charge the battery at a faster rate than does the float mode. The output of the charger may vary considerably when first turned on, depending upon the charge state of the battery. If the battery is almost fully discharged, the charger will supply its maximum rated current and will be in the current limit mode. As the battery charge is restored and the current demand decreases, the charger will automatically switch from the current limit mode to the float or equalize voltage mode, depending on the position of the float/equalize switch. Once the float or equalize mode is reached, the charger output current will gradually decrease, while the float or equalize voltage is maintained. If the

93

battery is at or near full charge when first turned on, the charger will assume the float or equalize voltage and the output current may be less than the current limit value. As noted, the output of the charger will be different depending upon the charge state of the battery. After the charger has been working for 24 hours, the general operation can be checked by switching between the float and equalize modes. When switched from float to equalize, the output (voltage and current) will increase as necessary to achieve the equalize voltage, and then the current will decrease slowly, to maintain the equalize voltage. When switched back to float, the output current will go to zero for a period of time as the battery voltage decreases to the float level, at which time the current will slowly increase as necessary to maintain the float voltage across the battery. In the float mode, the battery is maintained in a fully charged condition. The control module, through information supplied by the shunt, limits the output current of the unit. If the output current reaches the limit or set value before the output voltage reaches its set value, the unit will be in the current limit mode with the ammeter showing the set current value. In the current limit mode, changes in load requirements result in the output voltage changing, while the output current remains steady. A direct short across the output terminals of the battery charger will put the charger in the current limit mode.

WARNING

Do not short the output with the battery connected!

If less than the current limit value is required to achieve the set value of output voltage, the battery charger will be operating in the voltage limit control mode. Normally, the current drawn by the load or battery is less than the set current limit value, so the battery charger operates in the voltage limit mode. In this mode, the output current varies per load requirements while the output voltage remains steady. The voltage limit modes include the float and equalize modes.

13.1.2 Battery Charger Alarms

1. There is a 10-second time delay on all alarms.

2. Alarms are non-latching and will clear when parameters return to normal.

3. All alarms are sent to the monitoring system and are recorded and annunciated via the HMI.

4. All alarms except 125-VDC low voltage are annunciation only and the control

system issues no action. 5. 125-VDC voltage low will result in a unit emergency trip initiated by the control

system.

13.4.1 Adjusting Generator Lube Oil Pressure The generator lube oil system has one DC driven pump and one gear-type pump powered by the generator rotor. The generator must be operating at synchronous speed to adjust the oil pressure. Off line or unit shutdown lube oil system functional test consists only of running the DC lube oil pump for 20-seconds and checking for adequate pressure. See Screen 136.

1. Operate the generator at normal operating speed.

2. Observe oil pressure at PT3004.

3. At the lube oil module adjust PCV3001 to read 30 PSIG at PT3004.

13.4.2 Adjusting Generator Lube Oil Tank Pressure

1. Operate the generator at normal operating speed.

2. Observe tank pressure at PI3003.

3. The setting of the tank pressure as new is - 4.5 inches of water. As the generator seals age the negative pressure will decrease. Close the valve on the roof mounted exhaust fan to maintain at least - 0.5 inches of water.

13.5 Watch Windows II Operation. Watch Windows II (WII) is a Woodward application program associated with the Micronet control system. It is used as maintenance and troubleshooting tool to view operating parameters and edit tunable values. WWII will be used when periodically recalibrating transducers.

13.5.1 Viewing a Tunable

1. Open up WWII by double clicking on the desktop icon or through Program Files from the start menu. A window will appear as shown in Screen 104.

2. Enter the IP Address of the unit you to access. On a one unit site the control will

have an address of "172.17.1.1". On a multi unit site the address will be "172.17.u.1". Where "u" will be the unit number (i.e. the IP address for unit 3 will be "172.17.3.1"). Then Click “OK”. Three windows will appear as shown in Screen 105.

98

3. Expand the directory in the left top corner of the Explorer window by clicking on

the + sign in the box to the left of the IP address window. This will expand all the folders as shown in Screen 106. Each folder has a tag associated with it such as A1_A01_CPU. The tag format follows the below convention:

• First set of characters:

A1 = Rack 1 of the Micronet Chassis A2 = Rack 2 of the Micronet Chassis

• Second set of characters:

A01 = Slot 1 A02 = Slot 2 etc.

• The third set of characters designates the type of card, the I/O on the

card or the channel on the card. Cards used include:

CPU Central Processing Unit MPU Magnetic Processing Unit DIO Digital Input/Output AIO Analog Input/Output DI Digital Input DO Digital Output THD Thermocouple LON Link Net SIO Serial Input/Output ACT Actuator VLV Valve Driver

13.5.2 View a Tag Name

1. To access A1_A05_AIO.PT803A.OFFSET, expand Folder A1_A05_AIO then expand PT803A. The Explorer window will appear as shown in Screen 107.

2. Left click on “OFFSET” and “Drag and Drop” this to the Inspector window on the

right. The Inspector window will now appear as shown in Screen 108. This screen also shows two other tags that have been called up in this same manner.

NOTE

Two of the tags have pencil symbols next to them and one has an eyeglass symbol. The pencil indicates that the tag is tunable and the value can be changed. The eyeglass symbol indicates “read only” and the tag cannot be changed or adjusted.

13.5.3 Editing or Changing a Tunable Value

NOTE

99

The up and down arrows to the right of the tunable that are highlighted in Screen 108. They are used to increase or decrease the tunable value. The right set of arrows is a coarse adjustment; the left is a fine adjustment. The value can also be typed directly into the value pane; however this is limited to a certain maximum percentage difference from the current value.

1. Use the arrows for adjustment until an exact desired value is unobtainable then

enter the value by typing directly to the display pane.

13.5.4 Saving a Tunable Value After a Change. After tunables are changed it is necessary to “save” them. If WWII is closed before this is done, all tunables that were changed will revert back to the last saved value. To save the new values:

1. Right click on the IP address displayed in the upper left corner of the Explorer window. A drop down menu will appear. See Screen 109.

2. Click on “Save Values” to save.

13.5.5 Calibration of Transducers. Refer to Screen 108 using a pressure transducer as an example. The process variable, or feedback/measurement, from the field is A1_A05_AIO.PT803A.AI_COMBO in units of PSIG. Refer to the site-specific I/O list and /or the P&ID’s to determine a variable’s units.

1. Using a calibrated source or “standard”, inject a known process variable, in this case pressure, into the transducer at the lower calibration value shown in the Checkout Manual. In this example the low value is zero PSIG that corresponds to a 4 ma output from the transducer.

2. To calibrate the device adjust the OFFSET for the low range or “zero” of the

device per 13.4.2 until the variable reads “zero”.

3. Inject a process variable at the upper calibration value. If the high range of this device is 20 ma = 350 PSIG, A1_A05_AIO.PT803A.AI_COMBO should display 350.

4. Adjust the .GAIN tunable until the variable reads 350. Alternate between the low

range and the high range until no further adjustments are required.

In summary, the OFFSET is used to adjust the “zero” or low end of the device range and the GAIN is used to adjust the “span” or high end of the device range. When the high and low values display correctly, save the tunables as per paragraph 13.4.4 this section. RTDs, Thermocouples and other analog input devices are calibrated using similar steps. Inject a known signal using a simulator or calibrating device at the lower and upper calibration values. Adjust the offset and gain as above to obtain compatible readings. 13.5.6 Customizing an Inspector. It may be desirable to set up customized Inspector files for various units of work such as calibrations, monitoring specific data or troubleshooting. Tabs in the inspector can be renamed using standard Windows tools. A tab may be added by clicking on the “+” symbol. Tabs may be deleted by clicking on the “-“ symbol.

100

Prior to exiting WWII the customized Inspector may be saved by using the File, Save As Windows options. Customized files may be opened at a later date by using the File, Open commands.

13.5.7 Exiting Watch Windows II

1. Click on the exit button or “X” in the top right corner of the WWII window. If changes have been made to the Inspector a Confirm window will appear. See Screen 110.

A. If the changes are to be saved click YES.

B. If changes are not to be saved, click NO.

Saving changes will allow future retrieval of this Inspector after opening WWII. This is useful if standard tables are to be set up per paragraph 13.4.6 this section. 13.6 Control Assistant. Control Assistant is a Woodward application program associated with the Micronet control system. It is used as a troubleshooting tool by the Operator to create graphs from data logs generated by the control system after a trip or after initiation of the data log by the Operator. See SECTION 11 – DATA SYSTEMS, Paragraph 11.1 – Fast Data Logger.
